Efficacy of psychological interventions for sexual dysfunction: a systematic review and meta-analysis

Sexual dysfunction is highly prevalent in the general population and associated with psychological distress and impaired sexual satisfaction. Psychological interventions are promising treatment options, as sexual dysfunction is frequently caused by and deteriorates because of psychological factors. However, research into the efficacy of psychological interventions is rather scarce and an up-to-date review of outcome studies is currently lacking. Therefore, we conducted a systematic review and meta-analysis of all available studies from 1980 to 2009 to examine the efficacy of psychological interventions for patients with sexual dysfunction. A total of 20 randomized controlled studies comparing a psychological intervention with a wait-list were included in the meta-analysis. The overall post-treatment effect size for symptom severity was d = 0.58 (95% CI: 0.40 to 0.77) and for sexual satisfaction d = 0.47 (95% CI: 0.27 to 0.70). Psychological interventions were shown to especially improve symptom severity for women with Hypoactive Sexual Desire Disorder and orgasmic disorder. Our systematic review of 14 studies comparing at least two active interventions head-to-head revealed that very few comparative studies are available with large variability in effect sizes across studies (d between -0.69 and 2.29 for symptom severity and -0.56 and 14.02 for sexual satisfaction). In conclusion, psychological interventions are effective treatment options for sexual dysfunction. However, evidence varies considerably across single disorders. Good evidence exists to date for female hypoactive sexual desire disorder and female orgasmic disorder. Further research is needed on psychological interventions for other sexual dysfunctions, their long-term and comparative effects.

Sexual dysfunction in multiple sclerosis

Multiple sclerosis is a chronic disease that commonly affects young adults who may be sexually active. Sexual dysfunction is a significant, but often underestimated, symptom of multiple sclerosis, affecting 50-90% of men and 40-80% of women. The types of sexual dysfunction can be categorized in terms of the normal sexual response cycle: sexual interest/desire dysfunction (reduced libido), sexual arousal dysfunction (including erectile dysfunction) and ejaculatory and orgasmic dysfunction. Sexual dysfunction may not only be due to lesions affecting the neural pathways involved in physiological function (primary dysfunction), but also result from general physical disabilities (secondary dysfunction) or psychological and emotional issues (tertiary dysfunction). Comprehensive management should address all these possible contributing problems. Specific pharmacotherapy is only currently available for erectile dysfunction. This review summarizes the available information about sexual dysfunction in men and women with multiple sclerosis.

Sexual health in hematopoietic stem cell transplant recipients

Hematopoietic stem cell transplantation (HSCT) plays a central role in patients with malignant and, increasingly, nonmalignant conditions. As the number of transplants increases and the survival rate improves, long-term complications are important to recognize and treat to maintain quality of life. Sexual dysfunction is a commonly described but relatively often underestimated complication after HSCT. Conditioning regimens, generalized or genital graft-versus-host disease, medications, and cardiovascular complications as well as psychosocial problems are known to contribute significantly to physical and psychological sexual dysfunction. Moreover, it is often a difficult topic for patients, their significant others, and health care providers to discuss. Early recognition and management of sexual dysfunction after HSCT can lead to improved quality of life and outcomes for patients and their partners. This review focuses on the risk factors for and treatment of sexual dysfunction after transplantation and provides guidance concerning how to approach and manage a patient with sexual dysfunction after HSCT.

Internal iliac artery embolization before endovascular repair of aortoiliac aneurysms with a nitinol vascular occlusion plug

PURPOSE: To evaluate the acute and midterm effectiveness of a novel vascular occlusion device for embolization of the internal iliac artery (IIA) before endovascular repair of aortoiliac aneurysms. MATERIALS AND METHODS: Between March 2005 and April 2006, nine men (mean age, 75 years +/- 5; range, 66-83 y) with aortoiliac aneurysms underwent bifurcated endovascular stent-graft procedures. All these patients were referred specifically for embolization. Pre- and perioperatively, eight patients underwent unilateral embolization and one underwent bilateral embolization of the IIA to prevent type II endoleak. Via a contralateral femoral approach with a 6-F or 8-F sheath, the embolization procedure was performed with an Amplatzer Vascular Plug, a self-expandable cylindrical device consisting of a nitinol-based wire mesh. Technical success, clinical outcome, and complications were evaluated. Follow-up at 3, 6, and 12 months was performed with clinical and radiologic examinations. RESULTS: IIA embolization was technically successful in all cases and no procedure-related complications occurred. Imaging at discharge and at 3-, 6-, or 12-month follow-up was accomplished in all nine patients. Control computed tomography and magnetic resonance angiography did not reveal retrograde perfusion of the aneurysmal sac, ie, type II endoleak. Three of nine patients (33.3%) reported symptoms of buttock claudication that did not resolve completely. Clinical symptoms such as bowel ischemia or sexual dysfunction were not observed. CONCLUSIONS: The midterm results of this study suggest that preoperative IIA embolization with a nitinol vascular occlusion plug during endovascular treatment of aortoiliac aneurysms is safe and effective.

Combination of Psychological Intervention and Phosphodiesterase-5 Inhibitors for Erectile Dysfunction: A Narrative Review and Meta-Analysis

INTRODUCTION Erectile dysfunction (ED) is an increasing health problem that demands effective treatment. There is evidence that phosphodiesterase-5 inhibitors (PDE5-Is) and psychological intervention (PI) are effective treatment options; however, little is known about their comparative efficacy and the efficacy of combined treatments. AIM The aim of this systematic review and meta-analysis is to evaluate the comparative efficacy of PI, PDE5-Is, and their combination in the treatment of ED. MAIN OUTCOME MEASURES Primary outcome was ED symptoms, and secondary outcome was sexual satisfaction of the patient. METHODS A systematic literature search was conducted in order to identify relevant articles published between 1998 and 2012. We included randomized controlled trials and controlled trials comparing PI with PDE5-I treatment or one of them against a combination of both. RESULTS Eight studies with a total number of 562 patients were included in the meta-analysis. The results of the included studies are inconclusive, though they show a trend towards a larger effect of combined treatment compared with PI or PDE5-I treatment alone. The meta-analysis found that, overall, combined treatment was more efficacious for ED symptoms than PDE5-I treatment or PI alone. Combined treatment was more efficacious than PDE5-I use alone on sexual satisfaction. No differences were found between PDE5-Is and PI as stand-alone treatments. None of the moderators (treatment duration, methodological quality, or researcher allegiance) altered the effects. CONCLUSIONS The combination of PI and PDE5-Is is a promising strategy for a favorable outcome in ED and can be considered as a first-choice option for ED patients. Stronger RCTs are required to confirm this initial finding. Schmidt HM, Munder T, Gerger H, Frühauf S, and Barth J.

Vocal cord dysfunction: dealing with aggressivity

QUESTIONS UNDER STUDY: Vocal cord dysfunction (VCD) is characterised by recurrent attacks of paradoxical adduction of the vocal cords during inspiration, accompanied clinically by dyspnoea attacks with inspiratory stridor lasting between minutes and hours. The aim of the study is to evaluate the self-perception of patients suffering from VCD and how they deal with aggressivity. METHODS: The Giessen Test (GT) and the Picture Frustration Test (PFT) were used on 6 patients with VCD. RESULTS: Five variables show significant differences between the patients with VCD and the values of the normative groups. VCD-patients show an idealized image of themselves, ie relaxed, open, sociable, and capable of devotion. They do not reject accusations against them by others and rarely make self-criticism. In conflicts they behave passively, thus blocking their expression of aggressivity. CONCLUSIONS: In many cases organic disposition and trigger stimuli are thought to be responsible for provoking dyspnoea attacks in VCD. However, the self-perception of patients and their way of dealing with aggressivity strongly suggests that psychosocial factors play a great role in the development of VCD. This requires not only symptom-orientated therapy but also psychological counselling.

Measures of endothelial dysfunction in plasma of patients with posttraumatic stress disorder

Posttraumatic stress disorder (PTSD) confers an increased cardiovascular risk. In 14 otherwise healthy patients with PTSD and in 14 age- and gender-matched non-PTSD controls, we investigated whether the categorical diagnosis of PTSD and severity of PTSD symptom clusters (i.e. re-experiencing, avoidance, arousal, and overall score) would be associated with plasma concentrations of three markers of endothelial dysfunction [soluble tissue factor (sTF), von Willebrand factor (VWF), and soluble intercellular adhesion molecule (sICAM)-1]. Compared with controls, patients had significantly higher sTF; this difference became nonsignificant when controlling for psychological distress. VWF and sICAM-1 levels were not significantly different between patients and controls. In the entire sample virtually all PTSD symptom clusters correlated significantly and positively with sTF and VWF but not with sICAM-1. The correlation between symptoms of re-experiencing and sTF was significantly different between patients and controls. Controlling for symptoms of anxiety and depression (i.e. psychological distress) rendered most associations between PTSD symptom clusters and sTF nonsignificant, whereas controlling for age retained significance of associations with VWF. Posttraumatic stress showed a continuous relationship with sTF and VWF, with the former relationship being partly affected by psychological distress. This suggests one mechanism by which posttraumatic stress could contribute to atherosclerosis.

Longitudinal associations between causal sexual relationships and stressful life events in emerging adults

Findings on the consequences of casual sexual relationships (CSR) are inconsistent and range from positive to negative outcomes. The longitudinal association between stressful live events and CSR was investigated in a random sample of 2844 Swiss emerging adults. Cross-lagged panel models with baseline, two- and five-year follow-up data showed that life events predicted more subsequent CSR across emerging adulthood. In contrast, CSR predicted life events only from the first to the second wave. Results suggest that the link between stressful life events and CSR was mainly explained by romantic breakups as stressful life event. Environment-related life events were not substantially associated with casual sexual relationships. Thus, engaging in CSR did not seem to be a general emotion-focused coping strategy in the context of life events nor can the engagement in casual sex be seen as a result of stressful life events affecting general self-regulation.
